STEEL SIDE-DUMP CAR.

SPECIFICATION forming part of Letters Patent No. 770,306, datedSeptember 20, 1904. Application filed July 3, 1903. Serial No. 164,199.(Ilo model.)

To @ZZ 71171.07??J it 711mm/ concern.'

Be it known that LWILLIAM Q. OLDEN,a citizen ot the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Steel Side-Dump Cars, ofwhich the following is a specification, reference being had to theaccompanying' drawings.

My invention relates to steel side-dump cars;

IO and one ot' its principal objects is to provide a new and improvedform of car from which the load may be dumped upon each side oi' thetrack.

Another object of my invention is to provide new and improved mechanismfor operating the swinging doors on side-dump cars, and particularly toprovide a new and improved form of mechanism by which the doors may beopened to dump the load and closed 2O again and by means of which theywill be automatically locked in both their closed and open positions.

Another object of my invention is to provide new and improved featuresof construc- 2 5 tion in steel side-dump cars hereinafter pointed outspeciiically in detail.

In the accompanying drawings, Figure Ifis a side elevation partially invertical longitudinal section. Fig. 2 is a side view oione of Fig. 3 isa top or plan view partially in horizontal section. Fig. 4. is anenlarged cross-section upon line 4 A ot' Fig. l. Fig. 5 is an enlargedcrosssection on line 5 5 of Fig. l. Fig. 6 is an enlarged detail, beingan end view of the carbody viewed from the right in Fig. l. Fig. 7 is anenlarged detail, being a section on line 7 7 of Fig. 5. Fig. 8 is anenlarged detail, being an end view oi' the car-body with the 40 partsoutside of the car-body removed. Fig.

9 is an enlarged detail, beingavertical longitudinal section of one endof the car-body. Fig. l0 is an enlarged detail, being an isometric viewoil the apparatus for opening and shutting the car-doors; and Fig. ll isan enlarged detail, being a modiiication of the parts shown in Fig. l0.

Referring to the drawings, l2 indicates trucks, of any well-known formand description, upon which the other parts of the car are supported.

13 indicates body-bolsters, which are preferably formed'oi' two platesoi' steel or other suitable material, strengthened by suitableangle-irons, and secured to and supported upon the trucks l2.

14. indicates side girders, which are preferably formed of severalplates of steel suitably riveted or otherwise secured together andsuitably stiii'ened by angle-irons 15,' so as to 60 form a girder andforming the sides of the car of the shape shown in Fig. E2. The sidegirders 14. are riveted. by means of suitable angle-irons, to lthebody-bolsters 13.

16 indicates the loor. which is preferably 5 formed of steel platesriveted together by means ot' suitable angle-irons. The iioor 16 isroot-shapedgthat is to say, it slopes downward upon eachside of itsmedian longitudinal line toward the side oi the car. The side girders14, as is best shown in Fig. l, are cut away in their centrallowerportion to form an opening 32 above the roof-shaped iioor, throughwhich the load oi' the car may be dumped. The openings 32 upon each sideof 75 the car are closed by the doors suspended from and hinged to theside girders in the manner hereinafter described.

The iioor 16 is suspended Jfrom the side girders by means ofgusset-plates I7, which 8O are connected to the side girders by meansot' ang'le-irons 18, riveted to the gusset-plates and to the sidegirders. (See Fig. 5.) The lower portion oi' the gusset-plates 17 iscomposed ot' two plates 19, riveted to the plates 17. 85 The plates 19are of triangular shape, as is best shown in Fig. 5, and are separatedfrom one another, so as to inclose and house over slots Q0, cut throughthe floor 16 upon each side and near the lower edges for the purpose oi'permitting the passage through them of levers connected with the doorsand hereinafter described. The plates 19 are secured to the floor of thecar I6 by means ot' angle-irons The plates I7, together with the plates19, form practically continuous supports or gussetl sills 30 extendoutward to the end ofthe car plates, which, as was said above, suspendthe floor 16 from the side girders 14. the ioor 16, cut away partiallyfrom below, as is best shown in Fig. 1, project outward through thesloping end plates hereinafter described and are secured to thebody-bolsters 13 by means of suitable angle-irons. The floor 16 isstrengthened by suitable angle-irons 22 riveted thereto.

23 (see Figs. 8 and 9) indicates an end girder, preferably formed of aplate of steel and riveted to the side girders by means of suitableangle-irons. 24 indicates end plates, which are secured by suitableangle-irons to the side girders 14. The end plates 24 slope downward andinward to positions between the trucks 12 and are secured, by means ofsuitable anglesirons and rivets, to the body-bolsters 13. .The plates 24are also cut away in triangular shape from below, asis best shown inFig. 8, so as to rest over the roof-shaped ioor 16, to which the endplates 24 are secured by suitable angle-irons and rivets. 25 indicatessteel plates, which are secured to the lower ends of the sloping plates24 upon each side of the triangular opening by means of suitableangle-irons 26 and rivets. They are also secured by suitable angle-irons26xL and rivets to the floor 16. The plates 25 are vertical and formpractically a continuation of the plates 24 to form the ends of thecar-body and inclose the same. I prefer to form the end girder 23, thesloping plate 24, and the plates 25 of separate plates, secured togetherby anglefirons and rivets, as this is the preferable form ofconstruction; but it is obvious, of course, that these portions might beformed of one plate bent to suitable shape.

From the above description it will be obvious that the side girders 14,floor 16, and end portions, composed of the end girders 23, slopingplates 24, and plates 25, form an opentop car, completely inclosed atsides, ends, and bottoms, with the exception of the opening left in themiddle portion at each side by reason of the cut-away portion of theside girders, (shown in Fig. 2,) as above described, for the purpose ofdumping the load.

Referring particularly to Figs. 1, 4, and 8, 27 indicates channel-irons,which extend across the car from side to side outside of the plates 25,to which they are secured by suitable rivets, as is best shown in Fig.8. 28 indicates plates which extend across from side to side below thefloor 16. The plates 28 extend outward above the channel-irons 27 andare secured thereto by rivets. The ends of the plates, as is best shownin Fig. 4, are bent downward to conform with the slope of the iioor 16and are secured thereto by rivets. The plates 28 are strengthened bysuitable angle-irons 29. 30 indicates center sills, which are preferablyformed of two channel-irons, as is best shown in Fig. 4, set parallelwith each other. The

The ends ofV and are adapted to contain draft-rigging 31, which may beof. any suitable form and description and supported by the center sillsin any suitable manner. As this draft-rigging forms no part of mypresent invention and may be of any approved form, it is believed itneeds no further description here. The channel-irons forming the centersill 3() pass through suitable openings in the body-bolsters 13 and aresecured to the body-bolsters by suitable angle-irons riveted to thebodybolsters vand to the channel-irons forming the sills 30. The sills30 are also secured by rivets to the channel-irons 27 and to the plates28.

As best shown in Fig. 1, the sills 30 extend only partially Linder thecar and may be called for purposes of description interrupted sills.Bymeans of their connection with the bod y-bolsters, with the floor, andwith the side girders of the car by means of the channels 27 and plates28 the floor of the car practically forms a continuation of the centralsills, and the buffing strains caused by the shocks on the car either inthe nature of thrust or pull are received first upon the draft-riggingand transmitted to the center sills 30 and thence distributed throughoutthe iioor and sides of the car. By thusinterrupting the sills aconsiderable saving in weight and cost of manufacture is brought about,and at the same time space is left in the center of the car to containand permit the free working of the mechanism hereinafter described foroperating the swinging doors hereinafter described.

33 indicates swinging doors,which are preferably formed of steel platesbraced by suitable angle-irons 34. The doors 33 are hinged at their topsto suitable supports 35, carried by the side girders 14, so as to lil-lin the opening caused by the cut-away portion 32 in the side girders 14between the lower edges of the side girders and the outer edges of thefloor 16. The doors 33, as is best shown in Fig. 5, are arranged toswing outward, so that when they are swung outward the load will bedumped, guided to the center or dis'- charge portion of the car by thesloping end plates 24 and toward each side of the car by the slopingfloor 16.

36 indicates a shaft which is journaled in one of the body-holsters 13and in suitable bearings 37 in the center of the car below the Hoor 16,and its outer' end, as is best shown in Fig. 1, projects outward beyondthe body of the car over the truck 12.

38 indicates a short shaft which is journaled in suitable bearings 3940, secured, respectively, to uprights 41 and to the plate 24. 42indicates a hand-wheel which is keyed to the outer end of the shaft 38.

43 indicates a lever which is keyed or otherwise secured to the end ofthe shaft 36 and when the doors 33 are closed lies normallyhorizontally, as is shown in Figs. 3 and 6.v

IOO

44 indicates a chain one end of which is secured to the shaft 38 and theother to the outerend of the lever 43. By rotating the hand-wheel 42 thechain 44 will be wound upon the shaft 38, the lever 43 lifted, and themain shaft 36 rotated.

45 46 indicate grooved pulleys which are keyed or otherwise secured tothe shaft 36 near the center of the car.

47 48/ indicate rock-shafts which are journaled in suitable bearings 49below the floor 16 and near each side thereof.

50 51 indicate pulleys which are keyed or otherwise secured,respectively, to the rockshafts 47 48.

52 indicates a chain which passes around the pulley 45 and,crossingitself, passes around pulley 50.

53 indicates a pin in the pulley 45, which passes through a link in thechain 52, and 54 indicates a pin in the pulley 50, which passes througha link in the chaink 52.

55 indicatesachain which passes around the pulleys 46 and 51.

56 indicates a pin infthe pulley 46, which passes through a link in thechain 55, and 57 indicates a pin in the pulley 51, which passes througha link in the chain 55. The chains 52 and 55 are provided withturnbuckles 58. /Vhen the lever 43 is raised, as above described, andthe shaft 36 rotates, the rockshafts 47 and 48 will be rocked inopposite directions by means of the chain-and-pulley connections abovedescribed.

59 60 indicate arms which are secured, respectively, to the rock-shafts47 48. As I prefer to build the car and construct these devices, two ofthese arms are located outside of each end of the car-bottom, with twoor more of these arms between them on each 4of said shafts. The arms 5960, as is best shown in Figs. 10 and 11, are arranged in pairs, with aspace between them for the connection with the bent lever hereinafterdescribed. termediate arms 59 60 are located opposite the slots 2O inthe floor above described.

61 62 indicate bent levers which are pivoted between the pairs of arms59 90, respectively, and extend over the rock-shafts 47 48, theirforward ends being pivotally connected with the bottoms of the doors 33.The levers 61 62, which are on the portions of the rockshafts 47 48between the ends thereof pass their connection with the arms 59 60 andwith the centers of the rock-shafts 47 48.

The position of the levers and arms with the doors closed is shown insolid lines in Figs. 4 and 5. The open position ofthe doors and theposition of the arms and bent The in*V levers are shown in dotted linesin the same figures. From these figures it will be seen that when thedoors are closed the centers of the pivotal connections of the levers 6162 with the doors and with the arms 59 60 are below the rock-shafts 4748, by which the doors are locked in their closed position against thepressureof the load until the lever 43 is raised. As soon as the lever43 is raised, so as to lift the pivotal connections of the arms andlevers above the rock-shafts 47 48, the weight of Ithe load willordinarily force the doors open to their farthest limit, carrying thelever 43 up with them. In case the doors should not, however, thus openby the pressure of the load they may be opened to their full eXtent byfarther rotating the hand-wheel 42, winding the chain 44 still fartherupon the shaft 38 and lifting the lever 43 with it, thus forcing thedoors open to their fullest eXtent. When the doors are opened to theirfull limit, as is best shown in Fig. 5, the arms and levers again passcenters, whereby they are held in their open position. Vhen it isdesired to close the doors, the lever 43 is thrown downward by hand andthe above operations are reversed.

Fig. 11 shows a modification of the mechanism for opening' the doors, inwhich links are used to connect the shaft 36 to the rockshafts insteadof pulleys and chains.

.Referring to Fig. 11, 36 indicates the central shaft, as abovedescribed, 43 the lever secured to the shaft, 38 the short shaft, 42 thehand-wheel secured thereto, and 44 the chain connecting the shaft 38with the lever 43, and all operating in the manner above described. 47 a48fL indicate rock-shafts iournaled in bearings in the same manner asthe rockshafts 47 48 above described. 59 60 indicate the pairs of armssecured, respectively, to the rock-shafts 47 48a. 61a 62 indicate thebent levers, pivotally connected atV their inner ends with the arms 59u60, respectively, and at their outer ends adapted to be pivotallyconnected with the lower ends of the doors 33. (Not shown in Fig. 11.)The construction and operation of the arms 59u 60u and bent levers 61a621L are precisely as above described in describing the correspondingparts 59 60 61 62. 63 indicates a bell-crank lever rigidly secured tothe shaft 36 near the center of the car and beneath the floor. 64 65indicate arms which are rigidly secured to the rock-shafts 47 u 48,respectively,and extend downward therefrom. 66 indicates a linkpivotally connected at one end with the arm 64 and at the other end withthe end of the bell-crank lever 63 nearest toA the rock-shaft 47a. 67indicates a link pivotally connected at one end with the arm 65 and atthe other end with the end of the bell-crank lever 63 which is nearestthe rock-shaft 48u. By rotating the hand-wheel 42 the lever 43 will belifted and the shaft 36 given a partial rotation, and by means of thebell-crank lever IOO 63 and connecting-links 66 67 the rock-shafts 47 48will be rocked, throwing the arms 59 and levers 6l 62 into the positionsshown in dotted lines in Fig. 11 and opening the doors. As theconstruction and operation of the said levers and arms are exactly thesame as above described, the doors will be locked in both their open andclosed positions, as above described. The construction shown in Fig. 11is therefore an equivalent of the construction shown in the otherfigures.

It will be of course obvious that in the operation of my improvedmechanism, whether in the form shown in Fig. IO or in the form shown inFig. 11, the construction is such that too great rotation of the shaftsin either direction is controlled and prevented. By referringparticularly to Fig. 7 it will be seen that the slot 2O is closed at thebottom. When the doors are in their'open positions therefore, vas bestshown in dotted lines in Fig. 5, the ends ofvthe levers 59 60 or 59 60shown in the two constructions, respectively, will Contact with thebottom of the slot and will thereby be Vprevented from rotating anyfarther. When the doors are in their closed positions, the bottom of thearms 61 62 or 61 62 in the construction shown in Fig. l1 will bear,respectively, upon the shafts 47 48 or 47 48, and this will be preventedfrom moving any farther and will check the further rotation of theseveral shafts.

That which I claim as my invention, and desire to secure by LettersPatent, is-
